ELECTRIC STORAGE BATTERY.

Application ledMay 18, 1914. Seri-al o. 839,190.

Be it known that I, KARoLA/KNOBLOCH, a citizen of the United States of America, and

.resident of Baltimore, Maryland, have invented certain Improvements in Electric Storage Batteries, of which the following isV a specification.. a

, rIhis invention relates to certain Improvements in the construction of the grid with the view to increase the life and eiiiciency l of the battery; and it consists principally in.

making thev conducting ribs of the grid straight from end to end, and in arranging the same in .lines which if suiiciently extended, would converge at a single point exterior of or beyond the frame of the grid.

In the further description of the said inc vention which follows, reference is made to theaccompanying drawing forming a part hereof, and in which Figure 1 is a faceor plan view of the improved grid with the central portion thereof removed; and F ig.A 2 an exterior edge view ofthe same.' Fig. 3 is a section of Fig. 1

Referring now to the drawing, 1 is the rectangular `frame of the grid, and2 the electric terminal which extends from the end a ofthe frame, and is .formed as a part thereof. y

3, 3 are the conducting ribs which connect 'i the end portions of the frame; andthey are angularly placed so that should they be extended beyondl the end a of the frame, as shown by the broken lines in Fig. 1, they wouldconverge at the imaginary point o,

which is as before stated exterior of, or beyond the frame 1. v

By .the construction described electric currents are drawn from all. parts of the grid and conducted independently to and distributed along the portion of the frame havin the terminal 2; and this without mai terial y departing from a uniform content .dif the bodies of active material as would be y Specification of Letters Patent.

within the frame.

4: and 5 arethe upper and the lower bars which serve to support the conducting ribs 3, and also to sustain bodies of active paste (not shown) between them; and to better the case were the ribs to converge at a point -adapt them for the latter function, they are ployed to effect any useful purpose, but

merely to admit ofthe easy withdrawal of .the pattern of the grid from the sand in the molding operation. l I have shown' and described what to me dappears to be the best form and construction of the grid, but it will be readily understood that many changes can be made in its construction, without aecting'the nature of the invention. Y v 1' I claim as myl invention y 1. Inv asto'rage battery grid, a frame, conducting ribs in the frame,arranged in converging lines leading to a point which is exterior of or beyond the grid, combined with supporting bars for the ribs which extend transversely of the same, the said bars being flush with the upper and lower edges of the frame and provided with laterally extending projections. Q

2. In a storage battery grid, the conducting ribs thereof arranged in converging lines -leading toward a point which is exte- .rior of or beyond the grid, combinedv with upper and lower supporting bars which are as seen 1n cross section..
